Specialized Aethos: Maroon Frameset and Dura-Ace R9200 Crankset

Here is how the Specialized Aethos looks, with the Maroon coloured frameset! The previous Champagne Pink frameset was replaced under warranty, and I got the chance to choose a new colour.

I decided to build it up again, with mostly the same components. There were a few components changes, but otherwise largely the same Dura-Ace R9200 2x12 speed specification.

Freshly built up with a new frameset and same Dura-Ace components!

Another view from the non-drive side.

Fresh PRO bar tape, with my ideal shifter angle and handlebar position.

Dura-Ace C50 wheelset is used for better aerodynamics, compared to the Dura-Ace C36 wheelset.

Everything is freshly cleaned

Just 6.7 kg including pedals! Lightweight road bike possible with this lightweight Aethos S-Works frameset.

Love the glitter that shows up under sunlight

One other modification that I later made to the Aethos is the crankset. I had previously been using the Dura-Ace R9100 crankset, which is designed for 11 speed but also works well with 12 speed drivetrains. It saves some weight over the 12 speed crankset, which is why I kept it on the Aethos.

Dura-Ace R9100 crankset: 610 grams
Dura-Ace R9200 crankset: 682 grams

However, now I decided to install the 12 speed Dura-Ace R9200 crankset onto the Aethos, to complete the groupset. There is a little weight penalty of 72 grams but I think it is not going to matter at all.

Full bike picture again, with the Dura-Ace R9200 crankset. Most people will not be able to tell the difference.

I don't have any other upgrades or modifications planned for the Specialized Aethos, as it is pretty much perfect. Highest spec frameset with highest spec drivetrain, there is nothing more I need.

Some old school signs can be found!
